PURPOSE:To make the quality of concrete uniform by positioning a vibrator on the top end all the time by a method in which the depth of the top end of concrete placed is measured, and according to the measured values, the winding amount of a winder for the vibrator is regulated. CONSTITUTION:In constructing a continuous underground wall, a reinforcing bar cage 3 is set in an excavated pit 1 filled with bentonite, and concrete is placed into the pit 1 through a tremie tube 11. In this case, the depth of the top end 7 of concrete is measured by a measure 9 having a weight 8. According to the measured values, the winding amount of a winder 4 is regulated. A concrete vibrator 5 is set on the top end 7 to make the quality of placed concrete uniform.
